Application Log Getting Flooded with Events 64 and 65

We have recently installed our certificate servers and issued certificates to all domain computers and users.  We have noticed that the Application event logs on all the user systems and terminal servers are getting flooded with events 64 and 65 that are informational only.  I am trying to find a way to eliminate these useless events.  I have tried looking for a GPO or something, but so far have been unable to come up with a solution

Any help would be greatly appreciated.
